The reason for the communications dropout one-and-a-half minutes into a four-minute-41-second deorbit burn is unexplained for now. CBS News space reporter Bill Harwood tweeted (@cbs_spacenews): “TMA14M: Comm dropouts during Soyuz entries are not unusual, but they usually don’t happen so early or last so long.”

Telemetry received at a ground station in Egypt confirmed that the Soyuz modules separately correctly, but it was not until Soyuz commander Samokutyaev was finally heard saying that everything was fine onboard that a sigh of relief could be uttered.
